Crusader 8.1 eng oil
Just purchased a 2002 356 aft cabin with crusader engines...looking to change the oil. Many articles on engine oils. I hear the 8.1 has flat cams and needs an oil with special additive (SJ) . Looking to do the correct thing here. What oil is best for that motor.. Engines hours are 550 . Your help is greatly appreciated.

Re: Crusader 8.1 eng oil
PV also gets 2 cans of the old GM EOS in each engine each change. This is not the stuff you currently buy in a plastic bottle.
I have many cans left from my drag racing days thankfully The older stuff had lots of zddp in it, much more than the current breed of EOS.
But then there are plenty of folks out there that say zddp is not needed. I ran with that thought until I wiped all three cams one weekend. So now I don't listen to the experts.

Re: Crusader 8.1 eng oil
Yes, he works for Exxon Mobile, but he wasn't selling me anything, and he uses it in all of his vehicles. I have been using it ever since.
Mercedes and BMW recommend changing Mobile1 every 13,000 miles or once a year for warranty coverage. The last Vette I had required the Mobile1 to be changed every 7500 miles or once a year. So these manufacturers have some faith in it.
With a boat that most of us run only a hundred hours or so a year, you can probably get by with most any decent oil, just a matter of personal choice.
2cents added.

Re: Crusader 8.1 eng oil
I use M1 in the cars.
My last Benz had 356,000 miles on the clock when I sold it. It's still running around town. Never smoked.
I changed the oil when FSS prompted me to do so - and was typically around 18,000 miles.
So I did maybe 20 oil changes in 356,000 miles.
And it ran smooth as silk.
Body rusted away.

Ya me too Mike. I get the synthetic longevity, but you can't get away from the corrosive combustion by-products accumulated in ANY oil. The longer the oil is left in there the more concentrated these by-products get. The effects (etching) this has on major internal components is noticeable to the naked eye. This is especially bad during the long winter layups. So personally, mineral oil or synthetic, I'm still changing at the end of the season, and if that's the case, longevity isn't a concern to me nor is using mineral oil, the cost however is a concern!
